South Korea says North Korea has resumed flying balloons in a likely attempt to drop trash on South Korea again.

South Korean activists sent balloons carrying K-pop and K-dramas on USB sticks to their northern neighbor on Thursday, days after North Korean balloons of trash and “filth” floated in the opposite direction.

South Koreans are alert for possible new launches by North Korea of balloons carrying rubbish into the South, a day after Seoul activists flew their own balloons to scatter political leaflets in the North.

South Korea's military said it was on alert for more trash-carrying balloons possibly arriving from North Korea on Sunday.Pyongyang announced a halt to the balloons on Sunday but days later, a South Korean group called "Fighters for Free North Korea" said it had sent 10 balloons with K-pop music and 200,

Following the suspension of the 2018 tension-easing agreement, South Korea is ready to retaliate against a new North Korean balloon campaign by restarting frontline live-fire drills or loudspeaker broadcasts of anti-North Korean messages and outside news. Such steps are likely to further enrage North Korea.

North Korea on Saturday sent a new round of trash-laden balloons towards the South, Seoul's military said, after anti-Pyongyang activists in the South said they had lofted balloons with leaflets against leader Kim Jong Un across the border.

A North Korean defectors' group said Saturday that it has sent additional propaganda leaflets critical of the North Korean regime across the border, heightening concerns that Pyongyang may resume sending balloons filled with trash in retaliation.

South Korean activists have once again taken to the skies in a unique form of protest, sending balloons over the heavily militarized border into North Korea, not with traditional propaganda leaflets alone,
